Embodiment Construction

[0079]In the following description, many specific details are explained in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar popularizations without violating the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation disclosed below.

[0080]The invention is mainly applied in the field of network communication. The following are the professional terms involved:

[0081]SDN: Software Defined Networking, which is an innovative new network architecture compared to traditional networks, which aims to completely separate the data plane and control plane of network equipment;

[0082]MPLS label: MPLS uses labels for data forwarding. When a packet enters the network, a fixed-length short tag is assigned to it, and the tag is encapsulated with the packet. During the entire forwarding proce...

Abstract

The invention discloses an end-to-end service monitoring method based on an SDN. The method comprises the following steps: performing path query on a service to be monitored to obtain the informationof each node on a path of the service; packaging a specific packet_out message according to the attributes of the service; on the basis of matching the specific packet_out message with a service stream, matching a specific flag bit; issuing the packet_out message to a head end node of the service, and meanwhile starting a timer of the service; finally forwarding the packet_out message to a tail end node of the service; and after a packet_in message sent by the tail end node is received, parsing the packet_in message at the same time, calculating the delay of the path of the service, and resetting the timer of the service, wherein the packet_in message is packaged by the tail end node according to the received packet_out message information. By adoption of the end-to-end service monitoringmethod disclosed by the invention, the end-to-end monitoring of the service is achieved, the normal forwarding of the data traffic of the service is not affected, the performance requirements of a controller are not increased, and the end-to-end service monitoring method can be applied to a large SDN.

Description

Technical field[0001]The present invention relates to the field of communication technology, in particular to an end-to-end service monitoring method based on an SDN network. The invention also relates to an end-to-end service monitoring device based on the SDN network.Background technique[0002]SDN (Software Defined Network) is a software-defined network. It is a new network innovative architecture proposed by the clean slate research group of Stanford University. Its core technology, OpenFlow, separates the control plane of the network device from the data plane and integrates it in the network. It realizes the separation of software and hardware and the virtualization of the underlying hardware, thereby realizing flexible control of network traffic, and providing a good development platform for core network and application innovation.[0003]In SDN, the data forwarding layer and the control layer of the switching equipment are separated, so the upgrade of the network protocol and sw...
